TUESDAY, Feb. 26 (HealthDay News) -- Procedures to carry out a highly refined, complex radiation treatment for killing tumors and sparing healthy tissue may vary more widely from one medical center to the next than previously thought, a new study suggests. “This study raises a very large and serious problem for the radiation oncology community because you cannot compare doses and hence clinical outcome between treatment centers,” said study lead author Indra J. Das, a professor of radiation oncology at the University of Pennsylvania.
